Apart from termites, what other insects bite wooden stairs?

There were moths before the wooden stairs were made, but they were still alive, so just spray some medicine!

The larvae of some kind of Coleopteran insect.

Dome, agrees with HSCJN.

Upstairs is right. Find a syringe to inject the potion from high to low (a normal insecticide solution will do).

It is the larva of the longhorn beetle.

Although the adults can sometimes cause more or less damage due to egg-laying and feeding on branches and leaves, the damage is generally not serious. The larvae in the trees often hinder their normal growth, reduce yield, weaken the tree's strength, and shorten their lifespan. When the damage is severe, it can lead to the rapid withering and death of the tree. Trees that have been eroded are often susceptible to the invasion of other pests and germs, and are susceptible to strong winds.

When wood is damaged, it will inevitably lose its quality and even lose its technological value and commodity significance. The stems and roots of herbaceous plants are infested by larvae, which can also cause crop yields, wilting or death. It has been repeatedly documented in the literature that the adults and larvae of a longhorn beetle can sometimes attack metal substances such as lead skin, lead wire, and so on.

In 1957, a project in Guiyang found that the lead skin of two cables was bitten by adult Songtianniu in the ** cable shipped from Shanghai, so that the internal copper coins were exposed.

Wood parasitic with longhorn beetle can also be used to cause damage to debris when it is made into wooden utensils. A bundle of books at the Beijing Xinhua Bookstore Storage and Transportation Company was invaded by a longhorn beetle larvae, which eroded a tunnel inside the five overlapping books. Therefore, the economic significance of the longhorn beetle is very significant, especially for fruit trees and forests, they are an extremely serious threat, and the losses caused to people are very large.

The longhorn beetle is a herbivorous insect, most of which harm woody plants, such as pine, cypress, willow, elm, citrus, apple, peach and tea, etc., some harm herbaceous plants, such as cotton, wheat, corn, sorghum, sugarcane and hemp, etc., a few harm wood, buildings, houses and furniture, etc., and are important pests in forestry production, crop cultivation and building wood.

References. I'm not sure about the specifics...

Friend, you'd better send **.

Second...

Reply. It is very likely that it is a larva of a longhorn beetle...

It may have been in the wood before the renovation...

Pour some lime water or potion into it.

There are also silverfish, it is specifically recommended that you go to a professional place to consult, ** on a pesticide shop called Harmony BMW, they understand this.

There's nothing to do, it's because the wooden ladder can't be treated, use some insecticide.

It's so simple, just paint the wood of the wooden staircase with diesel, and I'm not kidding you.

Termites must have grown ......It's terrible, I can eat it all for you.

It's better to ask for help from a professional termite killer, and ordinary methods can't do it.

Go buy an insect-proof spray paint, the kind of transparent special paint that can protect the wood and last a little longer.

Not termites, but a very small beetle, soaked with the pesticide dimethoate.

The spray that kills mosquitoes will do.

Remember that there is a pesticide called "dichlorvos".

It shouldn't be termites, it's insects brought in the wood, and now they hatch and become insects and bite out.

Yes, it should be termites, as soon as termites are found, they should immediately ask a professional termite removal, or the gains outweigh the losses, don't save this money.

Termites, termite powder is required to do so**.

It's termites that eat it, just make up for it, and then sprinkle some insecticidal water.
